chamber 2 is full of water gas cannot enter. rTherefore, I provide a deformable means, as a rubber ball 2l, below the cap l1 to provide gas space. is carbonated water is drawn from the outlet 23 in the bottom of chamber 2 the buoyant ball 2l descends and the snift valve i5 drops from its seat 17, allowing' accumulated air to snift away. lNhile the gas valve is open' there is 120 pounds pressure in the carbonating chamber and as the dispenser is opened the water level falls under this pressure until water pressure in pipe 9 overcomes pressure in the carbonator chamber. rhen the fresh water rises and closes valve l5 by ball 2l. Fresh water enters from the pipe 7 while carbonated water is flowing out and when the ball 2l is lifted it presses the snift valve l5 to its seat 17 and snift is cut off.

lllhen the chamber is again full of water the ball closes the port 17a to prevent water from getting to the snift line 19. Gas pressure equalization is established through the bleed port .9.0.

The present system provides a master valve device normally opening the gas line 22 and normally closing the snift line 19 and the fresh water pipe 9.

The master device has a water valve lV, a gas valve G, and a snift cock S. The pipe 9 connects to the outlet from the valve whose supply side is attached by pipe 9a to precooling tank l0 which has a branch 9c for ice'water to draft arms D.

lt is very desirable to provide a positive safety against any back flow from the carbonator to the water tank pipe 9, which is connected to tank 10, and so avoid expensive loss of gas by leakage past the usual check valve V. rlfhe water valve lV is provided to assure no leak past the check to the tank lO.

rl`lie snift tube 19 leads to cock S, and from this to a receiver R. The gas pipe leads to gas cock (l having` a supply line 26.

The cock G is automatically opened and valves W and S are automatically closed preferably by a master device as a spring thrustrod P.

A feature of the invention is provision of multiple draft-arms D at the counter or at suitable locations adapted to receive carbonated water from the single carbonator chamber 2, under control of the master water valve lV. Means are provided for operating the master valve device (lV-SG) from the location, or station, of any of the draft arms D.

From the out-let Q3, in the bottom of the chamber 2, extends a carbonated water conduit 24, having branches 25 to the draft arms D, and having' a valve 27 suitably connected to a manually operated mechanism, including rod P linked to the valve 27.

At each station is a. counting instrument D to register each opening of the station draft arm valve by the attendant. rllhe register may be connected to any operating station part elfecting the valve il?. This valve must be opened before any liquid will flow from the opened draft-arm.

Normally the gas is passing to the chame ber 2 through the open ,gas valve Gr and the water is saturated by the which, being of higher pressure than that in the water line 9, tends to flow past check valve V and cause a constant loss as well as to allow the water in the carbonator to flatten. But in my present apparatus this loss is prevented by the main valve lV, which is a tight and positive cut off when closed. So, also, the gas cannot leak back to the precooler l0 or pass to thc ice-water pipe 9C.

rllhe operation is as follows:

The attendant at any station, desiring to dispense carbonated water from the near draft-arm, depresses his station arm 28 and this acts to open the carbonated water valve 27. As the arm is operated it pushes a bar 30 and this causes a lever 3l to pull up the rod P which throws gas valve G to close and cut off gas flow, and will positively open the valves lV-S to supply pre-cooled water to the chamber through the stand pipe 9, and at the same moment open the sniit line 19 to let out air and open carbonated water valve 2T.

The water supply pipes are all large enough to supply plenty of fresh water in event several of the draft-arms should be After accumulated open at the same time.

chamber begins to air is forced outand the lill with fresh water means) rises and closes the snift valve l5 against seat il'. Any number of the levers 3l can be actuated after master valve device, as rod P has been shifted by another, and the action of each arm will be counted or registered by its register l. The rod will be effective until thel last lever (in use) is released, and then is restored by it-s spring 32 and the valve device vW5-G set normal.

Vfhen the rod P is restored, the gas is turned on by cock G. It Hows to the chamber 2 and exerts a compression on the water which compresses the deformable (compres sible) device 2l which therefore provides additional space allowing entrance of the gas at the bottom of the chamber.

The entering gas wliirls from saucer to saucer and hood to hood in the chamber and thus has ample time, and large area of con tact, for absorption'by the water. lVhen the gas pressure is fully established in the chamber it works past the ball 21 and bleeds through the port 20. This equalizes pressure in the snift line to valve S and allows the valve 15 to settle when the ball again falls away.

In Figs. 6 and 7 is shown a draft-arm the ball (or equivalent providing for selection of any of a variety of syrups from jars J, and for a combination of syrups or of a syrup and water. The structure includes a manifold M to which is connected a series of tubes 41 from the jars J to a draft arm. A head block 42 has ports 48 from the tube ends to its bottom face against which bears a valve d'sc 45 having a single port 46 registering with a port 47 in a bloclr 48. This block supports disc 45 and has a king-pin 49 with a ball-bearing race 50 in the head block. The ports 43 terminate in a circular row'in the face 44y so that when the valve block is swung around the port 46 may register with any port43.

firm 28 is pivoted in a bracket (not shown) on block 48 and has a lug 28eL to engage the near end of the bar which is thrust forward by its spring 51 in the block. TJnder the block is a measuring cup 52 having a guide 58 for a valve stem 54 on. whose upper part is a valve disc 55 thrust against the bottom of block 48 by a spring 56 so as to normally close duct 47 leading from port 46 in the disc 45.

The cross-bar 30, in the block 48, has a cam 8OEL engaging the top end of stem 54 and has a notch 80b back of the cam. If the cross-bar 8O is apposed to the heel of the lever 81 then when the arm 28 is pressed down the aar not only acts on lever 31 to pull up the master valve rod P but also pushes down the valve 55 and opens duct 47 allowing flow to the cup 52. lllhen this is full a signal discharge flows through a small passageway 58 leading from the upper end of stem 54 out at its bottom. This will provide for timing carbonated water while a bottom valve 59 on the stem 54 closes the outlet from the cup. To give full stream discharge the cam-bar 8O is pushed over until the stem slips up into the notch 80h; valve 59 lifting from the outlet seat 60. To select a servite tube port 48, the arm is thrown laterally and this swings the valve port 46 to the desired port, or to a position to register with two of the ports when a mix is desired.

After register is obtained as shown by an indenr segment 62 on the head, the arm is then depressed one step and liquid flows to the cup while the valves 55-59 are depressed. Vwlhen the cup is full this is indicated by flow from passageway 58. Then the arm is released, valve 55 moves up closing port 47, and the bar 80 is swung around to register with carbonated water valve lever 31. Handle 28 is then-depressed two stepsto bring bar notch 801 over stem 54 and move valves 554-59 to neutral positions for free flowing of carbonated water from a tube 41 and through cup 52. The cam bar 8O is apposed to lever 81, at only two positions to serve carbonated water. The segnient 62 has two index notches to permit such being operated by registering position, and also-has a deep notch for fresh water service.

Fresh water is discharged when the bar 8O engages a lever 65 having a` heel disposed to be so engaged, attached to a water valve 66 Fig. 1. Suitable connections from each draft arm D, are made to actuate the master valve rod P. d These may include Vroclr shafts 67 with cams 67a to engage a lift plate 68 attached to rod l), the roel: shafts the respective station draft arm rods P and levers 81.

A feature of this invention is to utilize gas or air pressure snifted oft from the carbonator to force syrup from a .l through its tube 41 to the head of any draft arm D. As shown', the snifted air is discharged into a receiver R from which it passes in pipes 69 to boXesor manifolds M into the bottom of which the jars screw. @ver each jar is a valve device to close the manifold hole when the jar is removed. This device includes a springing diaphragm 7 O having a central nipple 71 free around the tube 41 leading down into the jar and having a valve seat 72 for the end of the nipple when the jar is screwed out. An applied jar engages aV ring 7 8 on, and forces baclr, the diaphragm so that air can pass intov the jar and dispel liquid through its tube 41.

fr suitable air pressure is auton'iatically maintained on the receiver R by a control means of suitable type; here shown as including an upright tube 75 of lli-form holding al heavy liquid, as mercury, proportioned to sustain, say tive pounds, of air pressure. lf the pressure goes up too high the mercury rises and spreads out in a pan 76 allowing the excess air and water coming over if any, to escape, whereupon the valve forming mercury will immediately counterbalance again to hold the pressure desired.

Means may be introduced in the carbonated water pipe 24 to measure out given quantities of carbonated water each serv ice. Such means isshown in Fig. cluding a cylinder 8O having a back flow check valve 81 at its inlet end and at its opposite end having discharge connections 25a for the different draft arms. ln the cylinder is a piston 82 having a valve member 83 to close outlets 88a to the discharges. From the piston extends a rod 84 forced outward by a spring 85 to close the outlets 88a. In the piston is a by-pass valve 86 held to its seat 87 by a spring with a pressure greater than the frictional resistance of the piston and rod in or against their guides. The master rod P when, pulledup, connects, as by dog 88, with the. rod 84 and shifts piston 8O a desired degree regulated by an adjustable screw stop 89, liquid moving past the valve 86 during the shift. When the dogJ is tripped, carbonated water and spring pressure returns the piston with a discharging 8 as in- I ltiil llt) action, overcoming` friction but not opening the l y-pass valve SG. rlhe pipe 25 is attached to the hach ot' hlocl' l2 in the .'i
